Many articles have been written about ssh server configuration, such as ssh service configuration under Linux. Here are just a few common commands for viewing ssh service information.

1 installation

apt-get install openssh-server

2. After completion, check whether ssh is enabled:

ps -e | grep ssh

If only there were:


server is not started

You can start it manually:

sudo /etc/init.d/ssh start

Or restart ES32en

The putty connection is now ready to use

rpm - qa | grep ssh can see ssh installation package in the system

rpm-ql openssh-3.5p1-6 View the installation information (such as installation path, configuration file, etc.)

ps - e | grep ssh view ssh services have run, if you have, you can see similar to the following content:

2254 ? 00:00:00 sshd

This proves that ssh is already running, and the process name is sshd

If not, you can run it with the following command:

root]#/etc/rc.d/init.d/sshd start

root]#service ssh start

Let's also look at the network connection of the ES73en service:

root]#netstat -ntlp

If you see the following:

tcp 0 0* LISTEN 22109/sshd

If the client (SecurCRT,putty, etc.) fails to connect, try to turn off the fire

Wall try: service iptables stop
